Exploration of orthorexia nervosa and diagnostic overlap with eating disorders, anorexia nervosa and obsessive‐compulsive disorder
ObjectiveOrthorexia nervosa (ON) is characterized as obsessional healthy eating that results in malnutrition and/or psychosocial impairment. Yet, ON shares theoretical overlap with eating disorders (EDs), especially anorexia nervosa (AN), as well as obsessive‐compulsive disorder (OCD). This study ai...

Yet, ON shares theoretical overlap with eating disorders (EDs), especially anorexia nervosa (AN), as well as obsessive‐compulsive disorder (OCD). This study aimed to further understand ON and its overlap with related disorders by assessing the ability of ON for detecting the presence/absence of threshold ED, AN, and OCD symptoms.MethodAn observational survey was completed by 197 participants recruited through eating disorder, dieting, and mental health support groups. Receiver operating characteristic (ROC) curve analyses determined the predictive ability of ON symptoms (assessed by Eating Habits Questionnaire [EHQ] orthorexia nervosa [OrNe] and healthy orthorexia [HeOr] subscales, and the Orthorexia Nervosa Inventory [ONI]) for detecting disordered eating symptoms (determined by Eating Disorder Examination Questionnaire [EDE‐Q] global cut‐scores), probable AN (determined by EDE‐Q cut‐scores and body mass index [BMI] |
